Skirt
From wipipedia.org
A skirt is a garment that covers the body from the waist to anywhere from the mid-thigh to the ankles depending on length. Unlike trousers or shorts, it is open at the bottom.
In modern western societies it is considered an exclusively female garment. It is therefore often preferred to trousers by transvestites and cross-dressers. Like other garments, it can be made of fetish matetials such as leather, rubber and PVC.
